[Lxc-users] Container failed, can't remove cgroup

Serge,

Thanks for the pointer.  That does seem like the right direction,
although it looks like this cgroup hierarchy already has a release
agent defined:

# cat /sys/fs/cgroup/systemd/release_agent
/usr/lib/systemd/systemd-cgroups-agent

And if I understand correctly, release agents can only be defined in
"root" cgroups (so I can't override this in
/sys/fs/cgroup/systemd/<container>/).  Time to visit the systemd list
again, maybe.
